PATENT JOHN REID, OF BROOKLYN, ASSIGNOR TO THE J. L. MOTT IRON \VORKS,OF NE\V YORK, N. Y.

ClSTERN FOR WATER-CLOSETS.

SPECIFICATION forming part of Letters Patent No. 280,243, dated June 26,1883.

No model.)

To all whom it may concern Be it known that 1, JOHN REID, of Brooklyn,in the county of Kings and State of New York, have invented anImprovement in Gisterns for \Vater-Olosets, of which the following is aspecification.

The object of this invention is to supply to the closet a preliminarywash before the closet is used, and an after-wash when the person leavesthe closets. Devices have been made with this object in view. Myinvention is for avoiding unnecessary consumption of water, and forrendering the mechanism reliable. I employ two pairs of double-aetingvalves,with water-ways and valve-seats, a main-supply water-cistern, andtwo flushing boxes or cisterns below the main cistern. The pairs ofvalves act in opposite directions, so that when raised the supplyopening to the preliminary-flushing box is closed, and the escape to thecloset opened. At the same time the supply-opening to the after-flushingbox is opened and the dischargeopening closed. As the valves descend,the reverse movement takes place, so that the after-flushing dischargesinto the closet, to thoroughly wash the same when the person rises fromthe seat or leaves the closet," the preliminary wash having been givenwhen the person entered the closet, or depressed the seat by sitting onthe same.

In the drawings, Figure 1 is a general plan of the cistern, and Fig. 2is a vertical section at the line 00 The cistern A is of a suitablesize, and preferably of cast-iron. .The inlet water-pipe B passes upthrough the bottom, or in through the side, in any desired manner. Thereis a valve or cook at O and afloat, D. These parts are of ordinaryconstruction, and serve to sup ply water from a suitable head, and shutoff the supply at a given level.

Beneath the cisternA are two water boxes or cisternsthe portion Econtaining the water for the preliminary flushing, and the portion F thewater for the after-wash. These boxes will usually be formed of onecasting, H,with a partition, J, that separates one box from the other.The position of this partition is indicated by dotted lines, Fig. 1. Thebox E, for

the preliminary wash, is much the smallest. The casting H is preferablybolted to the under side of the cistern A, the joint being madewater-tight by putty or cement.

Below the boxes E F there is the water-way K and a pipe, L, leading tothe water-closet.

At M and N there are two vertical pipes rising as high as thewater-level, and opening through the bottom of the cistern A into theboxes E F, so as to admit air and to form overflow-pipes to the cisternA-the same as usually provided in water-closet cisterns andservice-boxes.

There are four valve-seats. Those marked a and Z; are in the bottom ofthe cistern"A. Those marked 0 d are in the bottom of the boxes E F,respectively, and open into the water-way K. The seat a. isdirectly over0, and b direct] y over (I. The valves 6 f are on one spindle, and thevalves g h are on the other spindle, and both spindles are connected bychains to the lever I. The fulcrum 3 of this lever P is above thecistern, and there is a chain or wire, 4:, passing from the end of thelever]? to the water-closet door, seat, platform, or pull, there beingsuitable intervening levers, so that the lever will be operated in thedesired manner to raise the weighted end I, and lift the valves when theperson commences to use the closet, and the lever will fall when theperson leaves the closet.

In the normal condition, when the closet is not being used, the valx ewill rest on'its seat I), and the valve f will be on its seat 0; hencethe valves h and 0 will be open. \Vater can therefore flow by the seat ainto the box E and fill the same, but the box F will be empty. If, now,the lever P is moved, the conditions are reversed; the valve 0 isclosed, shutting oil the inlet to E, and the valvef is raised, so thatthe water from E rushes to the closet, giving the preliminary wash. Bythe same motion of the lever P the valve 71. is closed and the valve 9opened, so that water runs into the afterfiushing box F; but it does notescape from the same until the lever P is allowed to return to itsnormal position, and the valve y closes, and the valve h opens andallows the contents of F to flush the water-closet, thoroughly cleansingthe same. The valves f and g are ordinary weighted valves, with elasticfaces closing upon circular raised seats; the valve h is shown as a diskwith aleather face closing up against the seat (I, with a spring, z, topress it to place, the valve itself sliding on its stem k. This allowsfor holding the valve to its seat by the spring, even if the lever Pdoes not receive its full movement, or there is any inaccuracy of adjustment. Vith the same obj ect in view, the spring Z is applied betweenthe stem m of the valves of and the lever P, so that it may yield, butalso hold the valve 0 to its seat when the closet is in use.

I prefer to make the valve 6 as a segment of cylindrical rubber, and tomake the seat a small and conical, so that the valve 6 acts as anelastic plug to the seat a. This seat may be small, as there is alwaystime for the box E to fill with water while the closet is not in use.

The usual guides or bridges should be provided for the valve-stems, andit is preferable to employ brass val veseats secured to the iron, asusual.

I claim as my invention- 1. The combination, with the water-closetcistern A and the water-boxes E F, of the lever P, the valve g, abovethe seat Z) and closing downwardly, the valve h, on the same stem andclosing upwardly against the seat (I, the valve f closing downwardlyupon the seat 0, the valve 0, upon the same stem as the valve f, closingupwardly against the seat a, and the connections between the respectivevalve-stems and the lever P, substantially as set forth.

2. The combination, with the water-closet cistern A andpreliminary-flushing box E, of the valve f and valve 6, upon the samestem andwithin the box E, the valve f closing down wardly upon theseatc, and the valve 6 closing upwardly against the seat a, and theconnection from said valves to the operating-lever P, as and for thepurposes set forth.

3. The combination, with the water-closet cistern A, after-flushing boxF, and water-way K, of the valves 9 and h, upon the same stem, the valve9 being within the cistern A, and closing downwardly upon its seat I),and the valve it within the water-way K, and closing upwardly againstits seat (I, a spring, t, below said valve h, and connection to theoperating-lever P, as and for the purposes set forth.

4. The combination, with the cistern A and water-boxes E F, of thevalves 0 f, within the box E, and at the inlet and discharge openings ofthe same, the valve 9, above the inlet, and the valve 71, below thedischarge-opening of the box F, and the lever P and connections to therespective parts, substantially as set forth.

5. The combination, with the cistern A and water-box F, of thevalve-seats b d, valves 9 and h, above and below the respective seats,the valve-stein 7c, the spring 2' to the valve 71, the lever P, andconnection from the same to the valve-stem, substantially as set forth.

Signed by me this 11th day of December, A. D. 1882.
